The only effective treatment for Sudden Cardiac Arrest (SCA) due to ventricular fibrillation is an electrical shock called defibrillation.  An automated external defibrillator (AED) offers the best chance for survival, especially when used quickly after a collapse. Sudden cardiac arrest knows no boundaries.  Defibrillators and training is evidenced to provide a critical resource to help a family member, a friend, or simply a passerby - save a life.  Defibrillation is an electrical current applied to the chest via an external defibrillator. In the community we use an AED. The electrical current passes through the heart with the goal of stopping the ventricular fibrillation and providing an opportunity for the heart’s normal electrical system to take control. Defibrillation helps the heart reorganise its own electrical activity so it can pump blood again.
